Application August 6, 1946, Serial No. 688,777

17 Claims. (Cl. 128-355) This invention relates, as indicated, to a hair extracting device, but has reference more particularly to improvements in the device which form the subject matter of my copending patent application, Serial No. 561,565, now Patent No..

prevent the hair from being clasped or gripped between the sleeve and head.

(b) The sudden application of rotary force to the hair being extracted, due to the fact that both the sleeve and the shaftare directly power driven, results in breaking of the hair above its juncture with the skin, leaving stubs of hair in the skin. These stubs of hair present an objectionable appearance of dots corresponding in color to the color of the hair. Moreover, these stubs are so short that they cannot be extracted until they have grown so sufficient length to permit them to be clasped between the end of the sleeve and the face of the head of the shaft. In other words, the sudden application of the aforesaid rotary force on the hair which is clasped by the device tends to very suddenly remove the slack in the hair, and tends to break the hair, in a manner analogous to that in which a slack fishline is broken under sudden pull.

The device is formed of an excessively large number of parts, a great many of which are unnecessary, and others of which are of complicated construction as well as difficult to manufacture and assemble.

. It i a primary object of the present invention.

Another object of the invention is to provide a device of the character described, the use of which reduces to a minimum such breakage of the hair as has been hereinbefore described.

A further object of the invention is to provide a device of the character described, which consists of a minimum number of parts which are of simple construction, relatively easy to manufacture and assemble, and which, as a whole, is long lasting, trouble-proof, and inexpensive to operate.

A still further object of the invention is to provide a device of the character described which removes hair in an extremely efficient manner.

Other objects and advantages of the invention will be apparent during th course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same.

Fig. 1 is a longitudinal cross-sectional view of a hair extracting device embodyin my invention;

Figs. 2, 3, 4 and 5 are cross-sectional views, taken on the line 2-2, 3-3, 4-4 and 5-5, respectively, of Fig. 1;

Fig. 6 is an end elevational view of the device, as viewed in the direction indicated by the line 6-6 of Fig. 1;

Fig. 7 is a fragmentary elevational view, on

an enlarged scale, of the right end portion of the device shown in Fig. 1;

Fig. 8 is a view similar to Fig. '7, but with the sleeve in its operative or hair-clasping position, degrees from the position shown in Fig. 'l, and

Fig. 9 is a cross-sectional view, taken on the line 99 of Fig. 8.

Referring more particularly to the drawings, the device will be seen to comprise a one-piece tubular handle I, having a bore 2 therein, which is counterbored as at 3 to provide a seat or shoulder 4.

Disposed within the counterbore 3 of the handle is a tubular sleeve 5, which extends substantially the length of the handle I, and one end 6 of which projects from the handle, the sleeve being journalled within the handle and being freely rotatable within the latter, without benefit of bearings of other anti-friction devices. The sleeve 5 is provided at one end with openended longitudinally-extending slots 1 and 8, which are disposed diametrically opposite each other, and which serve a purpose to be presently described. The other end of the sleeve 5 is provided with a substantially semi-annular thrust surface 9, and a second substantially semi-annular surface H], the plane of which is offset rearwardly from the plane of the surface 9. The surfaces 9 and H] are interconnected at their ends by inclined surfaces or ledges i l and I2, which constitute cams.

Disposed Within the sleeve of the device is a shaft l3, the major portion of which is hollowed out, as at I4, to decrease the weight thereof. The shaft 13 is of slightly smaller external diameter than the internal diameter of the sleeve 5, and is provided, adjacent its ends with portions I5 and IB of enlarged external diameter, forming bearing surfaces by-which the shaft is supported in the sleeve.

The shaft I3 is further formed to provide a head I! having an annular face 18 which is adapted to cooperate with the surface 9 of the sleeve to grip or clasp hair and remove the latter.

The shaft l3 has threadedly secured to the rear endthereof a shaft I9 having a head 20 at its rear end. Disposed about the shaft i9 is a pair-of spaced thrust members or washers 2i and 22, between which a compression coil spring 23 is interposed. The washers 2! and 22 are provided at diametrically opposite points of each with tenons 24 which extend into the slots I and 8. The spring 23.exertsa force tending, on theone hand, to move the sleeve 5 to the. right, as viewed in Fig. l, and on the other hand, to move the shaft I3 to the left, so that there is a constantly acting resilient force tending to move the surfaces 9 and I8 into contact with each other to perform the hair extracting function to which reference has been made.

The sleeve 5 is adapted to be positively and directly driven by a driving member 25 which is journalled in the bore 2 of the handle. The member 25 has a forward portion 26 which extends into the rear end of the sleeve 5 and is provided with a. pin 21 extending diametrically therethrough, and the ends of which extend into the slots 1 and 8 of the sleeve, so that when the member 26 is driven as by threadedly connecting a power-driven flexible shaft (not shown) thereto, the sleeve will be driven. The member 25 is also provided with an annular recess 28 in which a snap ring 29 is mounted. The member 25 is free tomove slightly in an axial direction in the bore 2, but is prevented from moving out of the bore by reason of the engagement of the ring 29 with the shoulder 4 of the handle, and from moving too far to the right by reason of the engagement of said ring with the end of the sleeve 5.

For the purpose of intermittently retracting the sleeve 5 as the latter is rotated, in order to free or release the hair which has been clasped between the surface 9 and I8, I have provided a member 30, which is secured to the forward portion of the handle I as by rivets or screws 3i. The member 30 extends forwardly of the handle and has a downwardly or radially-inwardly extending portion 32, which extends into the space between the enlarged portion [6 of the shaft 13 and the surface 18 of the head 11, being of a thickness corresponding with the length of this tated by means of a power-driven flexible shaft, and, through the pin 21, transmits its rotary movement to the sleeve 5. As the sleeve 5 is rotated, it is also reciprocated so as to intermittently cause the Surface 9 of the sleeve to come into engagement with the lace I8 of the head I! of the shaft l3, and at such time, hair may be gripped or clasped by such surfaces. The movement of the surface 9 of the sleeve toward the face 18 of the head H is effected automatically due to the action of the spring 23. Movement of the surface 9 away from the surface l8 for the purpose of releasing the hair which has been thus gripped or clasped is effected by the portion 32. of the member 30. As the sleeve 5 rotates is a counterclockwise direction, as viewed in Fig. 9, the portion 34.of the member 30 comes into engagement with the inclined cam surface ll of the-sleeve, causing the sleeve to be retracted to the position shown in .Fig. '7, and the sleeve is maintained insuch retracted position for approximately one-half of the revolution of the sleeve, corresponding to movement of the sleeve through the arc indicated between the arrows in Fig. 9, which are is equivalent in length to the arc of the surface 9.

The aforesaid arc also corresponds to theportion of the devicewhich is to be applied to the skin for the purpose of extracting hair, and in order to avoid placement against the skin. of that-portion of the device which is not effective to remove hair, the member 30 may be provided with a guard indicated by the broken lines 35 in Fig. 9 which extends over the ineliectiveportion of the space between the sleeve and head.

In the event that the sleeve 5 is rotated in a clockwise direction, as viewed in Fig. 9, the portion 32 of the member 30 comes into engagement with theinclined cam surface 12 of the sleeve. causing the sleeve to be retracted to the position shown in Fig. '7. The effective portion of the device, in. that case, is. attheopposite side of the device. from that. shown in Fig. 9, and in such event, a guard disposed at the oppositeside of the device from that. shown in Fig. 9 is to be employed.

In order to insure that the. surface 9 will come into contact with the surface i8 and will not be obstructed from sodoing. by theportion 32 of the. member 30, the distance between the offset. parallel planes of the surfaces 9 and I0, is, as clearly shown in Fig- 8, slightlygreater than the glaickness of the. said portion 32 of the member Themember-3il performs adual function. Its. primary function has already been described. It also functions to strip or removehair, skin and other foreign matter which might otherwise ac-. cumulate between the sleeve and head of the device. For this purpose, the sharp edges 33 and 34 are effective. to strip from the shaft l3 hair or other matter which. adheres to theshaft. At the sametime. the rear edges of the portion 32 of the member 30 are effective. toremovehair and other matter which adhereszto the surfaces 9, [0, H and I2 of the sleeve, and thesfront edges of the portion 32 of the member 30 are effective to remove hair and other matter whichadheres to the face I8 of the head I].

It will be noted that the shaft I3 is not positively rotated, but is free to rotate independently of the sleeve, rotary movement being indirectly transmitted to the sleeve by the shaft through the medium of the hair which. is beingextracted. This permits a slightslipping of the hair just prior to the clasping of the hair between the sleeve and head of the device, which, in turn, permits the hair to straighten out prior to its being fully clasped and removed from the skin. This prevents breaking of the hair above its junction with the skin, and thereby avoids leaving stubs of hair in the skin.

It will be further noted that the device consists ofa minimum number of parts which are of simple construction, relatively easy to manufacture and assemble, and which, as a whole, is long lasting, trouble-proof and inexpensive to operate. In particular, it may be noted that there is no end thrust on any of the internal parts of the device, since all such end thrust is taken up by the member between the end of the sleeve and the head of the shaft. Moreover, no means is required to drive the shaft, and the sleeve and shaft can be assembled as a separate unit outside of the handle and then inserted into the handle and maintained in position by the member 3|]. Secondary manufacturing operations, such as drilling, slotting and threading are thus reduced to a minimum.

It is to be understood that the form of my invention, herein described, is to be taken as a preferred example of the same, and that various changes may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.
